return value: **`sequencer`** (To allow method chaining)
## Creating a User Interface
Image Sequencer provides the following events which can be used to generate a UI:
* `onSetup` : this event is triggered when a new module is set up. This can be used,
for instance, to generate a DIV element to store the generated image for that step.
* `onDraw` : This event is triggered when Image Sequencer starts drawing the output
for a module. This can be used, for instance, to overlay a loading GIF over the DIV
generated above.
* `onComplete` : This event is triggered when Image Sequencer has drawn the output
for a module. This can be used, for instance, to update the DIV with the new image
and remove the loading GIF generated above.
* `onRemove` : This event is triggered when a module is removed. This can be used,
for instance, to remove the DIV generated above.
How to define these functions:
```js
sequencer.setUI({
onSetup: function() {},
onDraw: function() {},
onComplete: function(output) {},
onRemove: function() {}
});
```
These methods can be defined and re-defined at any time, but it is advisable to
set them before any module is added and not change it thereafter. This is because
the `setUI` method will only affect the modules added after `setUI` is called.
The `onComplete` event is passed on the output of the module.
In the scope of all these events, the following variables are present, which
may be used in generating the UI:
* The object `identity`
```
identity = {
stepName: "Name of the Step",
stepID: "A unique ID given to the step",
imageName: "The name of the image to which the step is added."
}
```
* The variable `options.inBrowser` which is a Boolean and is `true` if the client is a browser and `false` otherwise.
Note: `identity.imageName` is the "name" of that particular image. This name can be specified
while loading the image via `sequencer.loadImage("name","SRC")`. If not specified,
the name of a loaded image defaults to a name like "image1", "image2", et cetra.
## Contributing
Happily accepting pull requests; to edit the core library, modify files in `/src/`. To build, run `npm install` and `grunt build`.
